Gentoo: GLSA-201406-13: memcached: Multiple vulnerabilities
Summary
memcached authentication could be bypassed when using SASL due to a flaw related to SASL authentication state. Also several heap-based buffer overflows due to integer conversions when parsing certain length attributes were discovered.
Resolution
All memcached users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/memcached-1.4.17"
